I came here to say exactly this, it's extreme hypocrisy. Cloudflare but also others from small to large services justify blocking IP addresses using the basis of "some IPs being a source of too much trouble"... but this doesn't make sense in an internet age of highly NATed and highly recycled IPs. One IP != one person, anything based on this assumption today is severely broken.
